Solis US version inverters have Seven working modes:
1. NULL 2. Volt-watt 3. Volt-Var 4. Fixed-PF 5. Reac-power 6. Power-PF 7. VgWatt-UL
Based on UL1741SA, working mode 1,3,4,7 can be used by grid operator.

Selecting “STD Mode. Settings” displays the sub-menu shown below:
2. Volt-Watt (Not Required)
Description: Inverter will change the active output power based on voltage change.
Note: This Setting is NOT required by UL1741SA Standards.
1.NULL
Description: Inverter is not under any working mode.
This function is for maintenance personnel only, wrong operation
will prevent the inverter from reaching maximum power.
3. Volt-Var (Default)
Description: Inverter will change the reactive output power based on voltage change.
There are TWO situations with different grid standards selected.
NOTE:
The following modes are for "UL-480V", "UL-480V-A".
